The electricity bill of an average household covered by the Voluntary Price for Small Consumers reached 36.42 euros so far in January, which represents a decrease of 50.1% compared to the same period last year. , when it amounted to 72.96 euros.
This is reflected in the electricity bill simulator of the National Commission for Markets and Competition (CNMC), which also reveals that compared to last month, the bill is reduced by 43% since the receipt amounted to 63, 89 euros on the same days of December 2022.
This strong drop in monthly terms, which will be limited in the rest of the month since in the last days of December the light registered its minimum of 2022, will allow a return to the downward trend experienced since September, which was broken in December with a rise close to 10%.
72.96 euros cost in the same period last year
On the other hand, compared to the previous year, January continues the trend of significant falls that began in October 2021, a month that ended with a series of 19 consecutive months of year-on-year increases that on many occasions even exceeded 60%, which explained much of the strong increases in the CPI last year.
Said evolution of the price of electricity corresponds to the bill of an average consumer with a contracted power of 4 kW and an annual demand of 3,240 kilowatt hours (kWh).
In June 2021, the new toll formation system and regulated receipt costs came into effect, with the three hourly billing periods. To carry out the price simulation, a consumption of 30% has been calculated in peak hours, 25% in flat hours and the remaining 45% in off-peak hours.
These fluctuations in the price of electricity are basically caused by variations in the cost of production, which increases when there is little contribution from renewable generation sources such as water and wind and many from more expensive fossil sources, especially gas or charcoal. It is also affected by other factors such as the price of CO2 emission rights.
